DESCRIPTION

       This reference page provides detailed instructions on adding PCMCIA card support to certain processors.

   Supported Configurations
       PCMCIA (PC Card) support is limited to the following capabilities: Support of selected ISA to PCMCIA bridge adapters Support on the follow-
       ing platforms: AlphaStation 255 AlphaStation 200 AlphaStation 400 AlphaStation 600 AlphaServer 1000 One modem card, specifically  Megahertz
       XJ2288 (28.8kpbs) Hot swap capability of PC Cards.

   Configuring a PCMCIA Adapter Board from the Console
       Before inserting the PCMCIA adapter board into your system, make sure to read the manual that came with the adapter from the adapter vendor
       and follow the instructions on how to connect the cables and install the board. Check your system documentation to find out  what  kind	of
       bus is available in your system and use the appropriate ISA or EISA instructions.

   Configuring a PCMCIA on an ISA Bus System
       If  your  system  has an ISA (Industry Standard Architecture) bus, use the following procedure to configure a card: If the system is an ISA
       bus system, the isacfg utility from the console must be used to configure the PCMCIA adapter.  Insert the PCMCIA adapter board  in  an  ISA
       slot  in  the  system and turn on the system.  To add a PCMCIA option to the platforms with an ISA bus, issue the following ISA option card
       configuration command at the console. The following example uses an AlphaStation 200 platform, but the commands should be the same  in  all
       three ISA bus platforms.  >>> isacfg -slot 1 -etyp 1 -dev 0 -mk -iobase0 3e0 /
       -irq0  14  -enadev  1  -handle PCIC-PCMCIA If the system is already using slot 1, select an unused slot number.	The IRQ (interrupt) number
       must not conflict with interrupt numbers assigned to other default devices on the system. The  system  hardware	manual	usually  indicates
       which IRQ numbers are already assigned.	The recommended IRQ number for the PCMCIA adapter is 14 (decimal).  If IRQ 14 is already used, the
       next best choice is IRQ 10 (if 10 is not already used by other devices).  When you issue the above isacfg command, the console should print
       out  the  following  line or something similar: type >>>init to use these changes After reinitializing the console, you can verify that you
       configured the PCMCIA adapter correctly by issuing the following command: >>>isacfg -slot 1 You should see the  following  screen  display:

       ============================================================= >>>

   Configuring a PCMCIA on an EISA Bus System
       If  you are installing the PCMCIA adapter on a computer with an EISA (Extended Industry Standard Architecture) bus, use the EISA Configura-
       tion Utility (ECU) to configure it. Invoke the EISA Configuration Utility (ECU), and specify that the PCMCIA adapter is present. Next, pro-
       vide a pointer to the aisa3000.cfg configuration file.

       Refer to your system hardware documentation for complete instructions on how to run the ECU program.

   Setting up a PCMCIA Modem PC Card for Use
       A PCMCIA Card is a dynamic device, not a static device that is present all the time in the system hardware).  The serial-line device driver
       is a static device driver.  Therefore, there will not be a corresponding acex entry created automatically when the first custom	kernel	is
       configured. This is because the system has no knowledge of the PCMCIA device at this time.

       To  automatically  create the acex entry for your PCMCIA fax/modem card: Ensure that you have the PCMCIA adapter configured in the console.
       Insert the PCMCIA fax/modem card into the slot.	For example, if you insert a fax/modem card in the slot 0  before  automatically  building
       the initial target kernel, the resulting kernel configuration file will contain the following line item: controller ace2 at pcmcia0  slot 0
       vector aceintr The installation will also create the device special file for this fax/modem card in the directory named /dev.  Using the ls
       command, you can display the file as follows: # ls -gl /dev/tty02 crw-rw-rw-   1 root	 system    35,	2 Oct 16 13:22 tty02

       If you did not have the PCMCIA fax/modem card inserted in the slot during System installation, add the following line to your system kernel
       configuration file (/sys/conf/HOSTNAME where HOSTNAME is the name of your system): controller		  ace2	  at *	   slot  ?  vector
       aceintr	If  you  plan  to  use	two  modem  cards  simultaneously,  add  the following lines to your system configuration file: controller
       ace2    at *    slot ? vector aceintr controller 	     ace3    at *    slot ? vector aceintr

       After modifying the system configuration file, use the following command to rebuild the new kernel and reboot the system: # doconfig -c

   Creating a Device Special File for the Modem Card
       Normally the system installation creates the following default tty0x device special files  in  the  directory  /dev:  crw-rw-rw-    1  root
       system	  35,  0 Oct 16 13:22 tty00 crw-rw-rw-	 1 root     system    35,  1 Oct 16 13:22 tty01 Two lines are present because most systems
       have two embedded serial lines. A system with a single embedded serial line creates only one tty00 entry in the /dev directory.

       To create additional device special files for the PCMCIA modem cards, use the MAKEDEV  utility  in  the	/dev  directory.  For  example:  #
       ./MAKEDEV ace2 MAKEDEV: special file(s) for ace2: tty02

       The  generated  special	file should look as follows: crw-rw-rw-   1 root     system    35,  2 Oct 27 14:02 tty02 If you intend to have two
       PCMCIA modem cards working simultaneously, create device special files for each card. For example: # ./MAKEDEV ace2 ace3  MAKEDEV:  special
       file(s)	for  ace2:  tty02 MAKEDEV: special file(s) for ace3: tty03 The generated special files should look as follows: crw-rw-rw-   1 root
       system	 35,  2 Oct 27 14:02 tty02 crw-rw-rw-	1 root	   system    35,  3 Oct 27 14:02 tty03

   Updating the /etc/remote File
       You must edit the /etc/remote file to add new access line definitions for the PCMCIA modem cards. If you have a 28.8kpb modem card and will
       be using the full speed, set the baud rate (br) to 38400 in the /etc/remote file as follows: line2:dv=/dev/tty02:br#38400:pa=none Note that
       line2 can be any name you determine to be used with the tip command to establish a connection.

       Once you insert a PCMCIA modem card and the system configures the card, the card can be used as for any other modem devices.

   Inserting a PCMCIA Modem Card
       To use a PCMCIA modem card, insert the card to one of the PC Card slots in the PCMCIA adapter. Depending on the adapter type, there may	be
       two front access card slots or one front access and one rear access card slot. When you insert the card into the slot 0, you should see the
       following message on the console terminal (or the Console Log window if using X11): # PCMCIA socket 0: card manufacturer: MEGAHERTZ product
       name: XJ2288 Configured: serial unit 2, type=16550A ace2 at pcmcia0 This example used the MEGAHERTZ XJ2288 fax/modem card.

       When  you  insert  a  modem card, an error message such as the following may appear on the Console Log window: socket 0: card manufacturer:
       MEGAHERTZ, unknown modem card inserted

       Using generic modem driver for this PC Card.

       PCMCIA socket 0: card manufacturer: MEGAHERTZ

       product name: XJ1144

       socket 0: Couldn't find usable config. for this card.  Please eject this PC Card.  This error occurs if the  card  requires  I/O  resources
       that  are already in use by other components in the system. If you see this error message, eject the card because it is not configured cor-
       rectly. A possible solution is to remove some other ISA/EISA devices in the system and reboot the system, freeing I/O resources that may be
       required.

   Removing a PCMCIA Modem Card
       Once  you are finished using the modem card, push the button next to the card slot to eject it. You should see the following message on the
       console terminal or console Log window: # stray interrupt on unit=2, intr_id=0 PCMCIA socket 0: PC Card removed

       This message is not always displayed when you eject the card. It only happens if the serial line driver generates  an  interrupt  when  the
       card ejected.

RESTRICTIONS

       The  following restrictions apply in this release: No support is provided for loadable device drivers for PC Cards.  If the system does not
       have any available IRQ (interrupt) numbers to assign to the PCMCIA devices, you cannot configure PCMCIA	devices.  To  support  one  PCMCIA
       adapter the system must have at least three unused IRQ numbers available.  One IRQ is for the adapter and the other two are for each PCMCIA
       socket.	Tru64 UNIX can support two PCMCIA adapters in a system provided that the necessary  resources  are  available.	In  some  systems,
       availability  of  interrupt lines will prohibit the use of multiple adapters. If you have sufficient resources and are going to support two
       adapters, configure the second adapter should to use the I/O address 3E2.  To use fax functions in a fax/modem PC card, a  commercial  UNIX
       fax  application  software program is required.	The Megahertz XJ2288 is the only modem card fully qualified on Tru64 UNIX.  However, other
       modem cards of similar type (both 14.4kpbs and 28.8kpbs) may work. The following is the list of modem cards that are known to  work:  Model
       XJ2288,	from  MEGAHERTZ  Model XJ1144, from MEGAHERTZ KeepInTouch Cardcard from ATT Paradyne PCMCIA V.32bis 14,400 Fax The selected ISA to
       PCMCIA bridge adapters are from SCM Microsystems. The SWAPBOX CLASSIC X2 Model MMCD-D2, which has the following features:  3.5  inch  front
       access  Two  slots  (type  II + type III) PC card socket Standard PC-AT 16-bit ISA bus interface PCMCIA Revision 2.X and ExCA compliant The
       SWAPBOX PREMIUM COMBO Model MMCD-FC2 has the following features: 3.5 inch, 1.44 Mbyte Floppy Drive Support.  One Type I, II, or III  front-
       access  PC  card  socket  One Type I, II, or III rear-access PC card socket Standard PC-AT 16-bit ISA bus interface PCMCIA Revision 2.X and
       ExCA compliant

       Other ISA to PCMCIA bridge adapters using the Intel i82365SL or a compatible device may also work.
